specific Embodiment 1
[0024] see figure 1 It can be seen that the yak fermented feed for improving growth performance of the present invention has 50 parts of coriander root as the main raw materials, 10 parts of highland barley, 10 parts of wheat bran, 20 parts of cottonseed meal, 10 parts of stems and leaves of Astragalus membranaceus, and the main raw materials are also added with fermentation bacteria. The bacteria are Bacillus subtilis, Saccharomyces cerevisiae, and lactic acid bacteria mixed strains, and the addition ratios of Bacillus subtilis, Saccharomyces cerevisiae, and lactic acid bacteria mixed bacteria are Bacillus subtilis 1‰, Saccharomyces cerevisiae 2‰, mixed lactic acid bacteria 2‰, and mixed lactic acid bacteria are Streptococcus faecalis and Lactobacillus acidophilus, the addition ratio of Streptococcus faecalis and Lactobacillus acidophilus is 8:2, when fermenting 1kg of main raw materials, add 1g Bacillus subtilis, 2g yeast, 1.6g Streptococcus faecalis, 0.4 g Lactobacillus aci...
specific Embodiment 2
[0025] see figure 1 It can be seen that the preparation method of the yak fermented feed that improves growth performance is characterized in that the processing steps are as follows: Step 1: strain activation: Bacillus subtilis and saccharomyces are activated by adding water according to the ratio of 1g:100mL for 0.5h respectively, and lactic acid bacteria are cultivated in MRS liquid basal culture, the activation time of strain activation is 0.5h, the fermentation time is 5d, the temperature is controlled at 30°C, and the initial moisture is 35%; Step 2: inoculation and fermentation: coriander root, wheat bran, highland barley, cottonseed meal, stem and leaf of Astragalus membranaceus Grind to 30-50 mesh, mix evenly in proportion to become the primary material, add the primary material to Bacillus subtilis, Saccharomyces cerevisiae, Streptococcus faecalis, Lactobacillus acidophilus in proportion, and mix well; Step 3: Cover the film : Fully mix the strains and fermentation r...
